Orghana (Orakina or Ergene Khatun) was an Oirat princess of the Mongol Empire and Empress of the Chagatai Khanate.
[3] According to Rashid al-Din, she organized a banquet for Hulagu when his army was marching through Central Asia to Iran in 1255.
In 1260, the Toluid Civil War broke out in the Mongol Empire with the death of Möngke, and his brother Ariq Böke dispatched Alghu to Beshbalik to consolidate his power.
After several battles, Ariq Böke sent Masud Beg and Orghana to Alghu to negotiate peace.
After the death of Alghu in 1266, Orghana nominated her son Mubarak Shah by her first husband, Qara Hülëgü as khan of the Chagatai Khanate.
